Problems solved by technology

At present, there are many types of cotton seed coating agents at home and abroad, but imidacloprid is used as the main component, especially when imidacloprid, thiram and carbendazim are made into a mixed agent at the same time, the seed coating agents used to prevent and control cotton seedling diseases and insect pests are very rare. few

Abstract

The present invention provides a seed dressing agent for controlling pests and disease of cotton seedling stage. Said seed dressing agent contains (by wt%) 12-17% of imidacloprid, 6-11% of thiram, 4-7% of carbendazim, 1-1.5% of OX-410, 1-2% of polyvinyl acetate, 1-3% of 1601, 0.5-2% of 690, 2-4% of 33#, 1.2-2.8% of thickening agent and the rest is water. Besides, it also contains proper quantity of aposematic color (stain) and defoaming agent. It can be used for effectively controlling rhizoctonia rot of cotton, cutworm and cotton aphid, etc.

Description

technical field [0001] The invention relates to a seed treatment technology, in particular to a cotton seed coating agent and a preparation method thereof. Background technique [0002] Seed coating agent is based on the types and hazard characteristics of crop seedling pests and diseases, and integrates insecticides and fungicides. The purpose of reducing seedling pests and diseases, thereby increasing crop yield. The principle of action is that the seed coating agent coats the surface of the seeds to form a seed coat with a coverage rate greater than 90%. When the seeds are sown into the soil, the seed coat only absorbs water and does not dissolve, forming a protective barrier around the seeds and acting as a protective barrier. To sterilize the seeds, while preventing the infection of soil-borne pathogens and the harm of pests, as the seeds germinate and emerge from the soil, the medicament is slowly released in the underground roots, and is transmitted to the unapplied ...
